W. 21. Foote — Meteoric Iron from Sams Valley, Oregon. 85 



specific gravity was found to be 7*794. Mr. Whitfield obtained 

 the following results on analysis of clean unoxidized drillings : 



Silicon 0-009$ 



Sulphur _ 0-056 



N ickel _ 9*160 



Cobalt _ 0*640 



Copper 0-016 



Carbon __ 0*100 



Iron . . _ 83-800 



93-781 

 Schreibersite 6-194 



99-975$ 



" There was no indication of phosphorus in the metal of this 

 iron other than that composing the schreibersite. This min- 

 eral, amounting to 6-19-4 per cent, was analyzed separately with 

 the following results : 



Iron... 65-13$ 



Nickel 20-93 



Phosphorus _ 13-94 



There was no manganese present in this iron, nor could any 

 of the rare or unusual elements be identified." 



A recalculation of the above figures, excluding the schreiber- 

 site, gives the following results. For comparison the Mount 

 Edith (^AVest Australia) analysis by Whitfield is given in the 

 second column.

Silicon 0*009$ 0'005$ 



Sulphur 0-059 0-005 



Nickel ._ _ 9-762 9'450 



Cobalt 0-682 0-625 



Copper. 0-017 0-013

Iron _ 89-357 89'500 



Phosphorus None 0*316 



99*992$ 99-931$ 



Estimating all the phosphorus in Mt. Edith as composing 

 schreibersite, 2*10 per cent of this mineral would be indicated.
